Specificaton of Letters Patent.

Patented Oct. 26, 1909.

Application filed April 13, 1909. Serial No. 489,552.

To all whom tt may concern: l

Be it known that I, JOSEPH C. SOHNEIDER, citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Horseshoe- Calks, of which the following is a specification.

This invention relates to farriery and refers particularly to a calk and the constructilondof a shoe to which the call: is to be app An Object of this invention is the provision of a calk which is detachable and which when positioned is in interlocking engagenent with an adjacent calk in order to prevent the rotation of the same and to thereby hold the edge of the calk in alinement with the shoe at the required angle.

The invention further contemplates the provision of a shoe which is provided at its forward or toe end with a novel seat for the reception of the calk in order to retain the same from rotary movement when the edge of the call: is brought into engagement with an obstacle in the roadway at times to rotate the same and to change the angle thereof.

A still further Object of the invention is the provision of a shoe and calk to be applied to the same which are of simple and inexpensive construction and which may be readily adapted to practical use so as to produce an economical and durable device.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which 2- Figure 1 is a perspective view of the horseshoe having the calks applied thereto and disclosed in an inverted position. Fig. 2 is a bottom plan view of the forward end of the shoe, and Fig. 3 is a detail perspective view of a pair of interlocking calks disclosing the same in a separated position.

corresponding and like parts are referred to the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings the numeral 10 designates the body of a shoe which is of common formation and which is provided at its opposite rear ends with apertures 11 which are disposed in pairs adjacent one another and into which are frictionally engaged the shanks 12 of the improved calks.

The forward or toe end of the shoe 10 is likewise provided with a pair of apertures 13 which extend entirely through the body portion and into which are adapted to be inserted the shanks 12 of the improved calks. The shoe 10 is provided with bosses 14 which are formed about the lower ends of the apertures 11 or upon the lower face of the shoe 10 while the shoe 10 carries bosses 15 formed upon the lower face of the same about the apertures 13. The bosses 15 are provided with opposite indentations or notches 16 which are of such a width as to admit of the resting of the upper end of the body portion of the improved calks therein in order to prevent the rotation of the same about the shank 12 as an aXis.

To prevent the rotation of the calks 17 when the same are positioned upon the shoe 10 the calks 17 are provided with tongues 18 and grooves 19 which are disposed upon the opposite extremities of the same and are adapted for interlocking engagement when the same are disposed in pairs within the apertures 11 and 13. x

It will be noted from the drawing that the calks 17 are otherwise of common formation, being reduced at their outer ends to form a beveled edge for engagemcnt with the roadway to form a firm gripping hold for the animal wearing the same and are secured to the shoe 10 by the forcing of the shank 12 thereof to frictionally engage within the apertures disposed in the shoe 10.

In applying the calks 17 to the shoe 10 the same are engaged in the apertures 11 and 13 disposing the tongue 18 of one, adjacent the groove 19 of the adjacent calk, the tongue 18 engaged within the groove 19 upon the insertion of the calks 17 within the respective apertures. By reason of the interlocking engagement of the tongues 18 within the grooves 19, the adjacent calks 17 are prevented from rotation about the shanks12 and are retained in position forming a continuous beveled edge for engagement with the roadway which is disposed at the desired angle and maintained in such position.

Having thus described the invention what is claimed as new is 1. A device as specified comprising a horseshoe having apertures disposed through the same in pairs, bosses formed on the under face of said shoe about said apertures, the forward of said bosses being provided with indentations oppositely formed therein, calks for engagement against said bosses and .formed on the opposite extremities of said calks for interlocking engagement wit-h the grooves formed in the opposite ends of the adjacent calks.

2. In conbination With a horseshoe having a plurality of apertures forrned therethrough of caiks carried by said shoe, shanks on said shoe to engage in the apertures and to retain said calks in pairs, bosses having l transverse indentations formed in said shoe about said apertures, the indentations adapted to receive the inner ends of said calks to prevent their rotation, said calks having grooves formed in the ends thereof and tongues vertieally disposed on the ends of said calks for engagement in the grooves to coperate With the identations to rigidly secure the calks from movement.

In testimony whereof I affixmy signature in presence of two Witnesses.
